Title: Limiting circuit for sound signal amplitude
Inventor: YOSHIDA HIDEO
IPC: H04N5/91
Filed: 1984-07-02
Abstract: PURPOSE:To improve the reproduced sound quality with no deterioration in the picture quality by setting an equal signal control level between the upper and lower sides of the waveform amplitude in order to increase an area which is free from the deterioration in the distortion factor of the sound signal in case the input is excessive for the sound signal to be supplied to a limiting circuit for sound signal amplitude. CONSTITUTION:Sound signals 1 and 1' are supplied to pre-emphasis circuits 2 and 2' and delivered 10 and 10' after the control given to their amplitudes from a limiting circuit 3 for sound signal amplitude and then the FM modulation received from voltage control oscillators 4 and 4' respectively. The circuit 3 connects the output of a stabilized power supply circuit 11 to resistances 12 and 13 and flows currents to constant current Tr19 and 21. An equal difference of potential is secured between the base potentials of the Tr19 and 21 and the output of the circuit 11 by setting the equal resistance value between both resistances 12 and 13. For the sound signal of a sound signal amplitude control terminal 22 which is decided by the base potentials of Tr19 and 21, an area free from the deterioration in the distortion factor is increased since the same signal level is secured between the upper and lower sides of the waveform amplitude and then the same sound signal distortion factor secured between the low and high frequency sides in case the inputs of signals 1 and 1' are excessive.

Title: Input and output terminal system
Inventor: FUJIOKA MASAHITO
IPC: H04Q3/545
Filed: 1982-08-03
Abstract: PURPOSE:To reduce the cost and to facilitate an easy operation of an input/ output terminal system, by having a switching connection between the 1st and 2nd input/output terminal device control parts under the control of a central processor. CONSTITUTION:A typewriter TYP is connected to a typewriter control part TYPCRLA or TYPCRLB via a typewriter switching part TYPCH, and a typewriter flip-flop TYPE/F stores the information on the above-mentioned connection of the TYP. Then the TYPE/F delivers a switching request to a central processor CC to switch the TYP to the part TYPCRLB from TYPCRLA if the TYP is not connected to the part TYPCRLB of a service device SVE. The processor CC delivers a switch control instruction to the part TYPCH via an interface part INT when the TYP is available to the device SVE. Thus the TYP is connected to the part TYPCRLB. The device SVE delivers a switching request again after its application. While the processor CC cuts off the TYP and connects it to the side of the controller CC.

IPC: H04J9/00
Filed: 1986-06-10
Abstract: PURPOSE:To eliminate that a transmitting speed is increased unnecessarily and to raise a transmission efficiency by using the violation of a bipolar signal. CONSTITUTION:At a transmitting side, a violation control signal is outputted when a condition information input IN2 is an 'ON' condition in a violation control circuit 1.

IPC: A23L15/00
Filed: 1995-06-01
Abstract: PURPOSE: To perform a short time of heating at high temperatures without deteriorating the quality of a material by passing liquid food through continuous courses, and simultaneously passing currents between adjacent electrode surfaces inside the courses. CONSTITUTION: Fluid food is preheated by passing it through a heat exchanger and is poured into an electric heating cell.

Title: System and device for decoding
Inventor: KONDOU SETSUKO
IPC: H04L1/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To compensate a loss in the continuity of sounds in the case of decoding and reproducing while eliminating the omission and error of transmission information caused by the degradation of communication quality by transmitting the encoded transmission information through a network, where the occurrence of temporary error is estimated, and performing error correction and temporary storage when recording that information. SOLUTION: A radio terminal 1 executes demodulating processing or the like to sound information received at an information reception part 13 through a radio channel and an antenna 11 and performs error correction through an error correction protocol terminal part 15 later. Further, a speaker 21 outputs the sound information, to which a decode part 19 performs decoding processing through a buffer part 17, as sounds. Besides, the buffer part 17 stores the sound information for 5 seconds and sends it to the decode part 19 continuously without interruption, and this sound information is decoded and reproduced by the decode part 19. Thus, even when hand-over is activated by the movement of radio terminal 1 and the radio signal is hit, the sound information is continuously decoded and reproduced without fail.
